/claim #17

Summary

Adds a dependency-free scientific-knowledge-graph/ MVP module for SCIBASE scientific knowledge graph integration.

Implemented coverage:

• Research object ingestion for papers, datasets, notebooks, and protocols.
• Deterministic extraction for concepts, gene-like symbols, tools, datasets, protocols, references, and DOIs.
• Author, affiliation, project, dataset, protocol, tool, concept, DOI, and research-object node types.
• Evidence-backed relationships for authored, affiliated-with, cites, mentions, uses, reuses, and co-occurs-with.
• Entity pages with citation contexts, related nodes, relationship evidence, and schema.org JSON-LD.
• Graph search and navigation payloads with domain, node-type, relationship-type, evidence, and text filters.
• Influence-path traversal between graph entities.
• Recommendation digest payloads for workspace sidebars or weekly emails.

Validation
